What it does

Study Vault is an agent skill from ten-builder/ten-builder. PDF/문서를 Obsidian StudyVault(학습 노트)로 변환합니다

Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/codebase-guide.md`, `references/quality-check.md` and `references/vault-templates.md`).

It sits in Documents & Office, covering PDF. It works with Obsidian. The repository describes itself as: AI로 10배 빠르게 빌드하는 방법, 직접 써보고 검증한 AI 실전 노하우.

When your agent uses it

  • Tasks that involve PDF

Example prompts

  • “/study-vault”

What it can do on your machine

Read from SKILL.md and the folder at commit 23d2a64. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pdftotext

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Study Vault loads about 718 tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 13 tokens; SKILL.md has 239 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~718
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 239 words (~718 tokens).
